The present paper reports the experimental and theoretical results for oblique reflection of weak shock waves. We introduce a modified three-shock theory to explain the well-known von Neumann paradox for weak Mach reflection. The theory proposed here considers the effect of slipstream divergence immediate behind a triple point. By giving the angle of slipstream divergence parametrically, we obtain some characteristics, such as the angle of reflection, around the triple point. We compare the numerical results thus obtained with experimental results. For weak Mach reflection, the modified three-shock theory gives physically realistic solutions, even when the von Neumann's classical three-shock theory has no solution. All the experimental data exist in the domain given by the present theory.
